- the open signal is the signal sensed by the first proximity sensor for detecting a window open activation input command, whereas the close signal is the signal generated by the second proximity sensor for sensing a window closing activation input command. If the open signal is greater than the closed signal, routine 100 proceeds to decision step 106 to determine if the open signal is greater than an open threshold, and, if so, determines if the ratio of the close signal to the open signal is less than an open ratio at step 108 . If not, routine 100 is done at step 122 .
- routine 100 proceeds to step 110 to determine if the open and close signals have been stable for a minimum time period, such as 100 milliseconds, and if so, activates the open enter state and the Wait_For_Release routine at step 112 . Otherwise, routine 100 is done at step 122 .
- routine 100 proceeds to decision step 114 to determine if the close signal is greater than a close threshold and, if not, is done at step 122 . If the close signal is greater than the close threshold, routine 100 proceeds to decision step 116 to determine if a ratio of the open signal to close signal is less than a close ratio and, if not, is done at step 122 .
- routine 100 proceeds to step 118 to determine if the open and close signals are stable for a predetermined time period, such as 40 milliseconds and, if so, proceeds to step 120 to set the open start equal to open, and to set the ratio start equal to a ratio of open to close, and enters the Wait_For_Pull state. Otherwise, routine 100 is done at step 122 .
- the Wait_For_Release state subroutine 200 is illustrated beginning at step 202 and proceeding to decision step 204 to determine if the open and close signals are less than a release threshold and, if not, is done at step 206 . If the open and close signals are less than the release threshold, subroutine 200 proceeds to step 208 to enter the monitoring state which returns to step 200 .
- routine 210 sets a ratio equal to the open signal divided by close signal.
- routine 210 determines if the open signal is greater than an open start value multiplied by parameter KD and if the ratio is less than the ratio state multiplied by factor KR, where KD is greater than one and KR is between zero and one. If the conditions of decision step 216 are met, routine 210 proceeds to step 220 to activate opening of the window and enters the Wait-For-Release state. Otherwise, routine 210 ends at step 218 .
- the proximity switch assembly 20 advantageously allow for activation of the window based on an object sensed with first and second proximity sensors on first and second sides and isolated by a ground layer.
- the system and method advantageously allows a user to effectively control the vehicle window without having to actuate a mechanical input lever and with reduced signal interference, and thereby providing for a robust switch assembly having fewer moving parts and which is cost-effective and easy to operate.

Thevehicle door 12 has amovable window 14, also referred to as a power window, that moves a glass window panel downwards in a first direction towards an open position and upwards in a second direction towards a closed window position. Thewindow panel 14 is generally actuated by a motor, such as an electric motor, typically in response to a user input switch. While thevehicle 10 is generally shown having a frontdriver side door 12 andmovable window 14 therein, it should be appreciated that thevehicle 10 may be equipped with a plurality of doors each employing a movable window, and the vehicle may be equipped with other movable panels that are actuatable to move in response to activation of a user input switch. - The
vehicle 10 is further equipped with aproximity switch assembly 20 for controlling actuation of themovable window panel 14. Theproximity switch assembly 20 is shown located on anarmrest 16 on the interior trim ofdoor 12, according to one embodiment.

Theproximity switch assembly 20 includes a first proximity switch having a first proximity sensor for sensing user activation on one surface and a second proximity switch having a second proximity sensor for sensing user activation on an opposite second surface. The first proximity switch senses user activation to activate thewindow panel 14 to move downward to an open position and the second proximity switch senses activation to move thewindow panel 14 upward to a closed position. - The

When thefinger 70 engages thetop surface 50A ofmember 50, thefinger 70 enters anactivation field 74 generated by the top first proximity switch which is detected and used to generate an input to open the window panel.

The seconddielectric layer 60 may include fiberglass and is disposed between theground layer 58 andsecond proximity sensor 64 to provide dielectric isolation therebetween.Dielectric layers - A
cover material 52 is shown formed surrounding theproximity sensors dielectric layers ground layer 58. Thecover material 52 may include a molded polymeric material, according to one embodiment. Thecover material 52 may include a material suitable for the armrest, such as a vinyl or leather material, according to other embodiments. The first andsecond proximity sensors cover material 52, according to one embodiment. Theproximity sensors cover material 52 or otherwise may be formed thereon or disposed between thedielectric layer cover material 52. According to another embodiment, theproximity sensors dielectric layers - The
proximity switch assembly 20 is further shown including aconnector 66 that provides electrical connections to the first andsecond proximity sensors connector 66 may include electrical conductors that connect between thecircuit board 68 and each of the first andsecond proximity sensors connector 66 also provides a ground line connection to theconductive ground layer 58 such thatlayer 58 is electrically grounded. Theconnector 66 may include printed circuits or wires that lead to printed circuits on the inner surface of thecover material 52, according to one embodiment. According to another embodiment, the circuitry traces may connect to circuit traces on thedielectric layers ground layer 58,dielectric layers second proximity sensors cover material 52. - In operation, the
first proximity sensor 54 generates afirst activation field 74 on and above the first ortop surface 50A ofmember 50. Thefirst activation field 74 is prevented from extending downward and onto the bottom or second surface due to theconductive ground layer 58. Similarly, the bottom orsecond proximity sensor 64 generates asecond activation field 84 that extends on and below the second orbottom surface 50B. Thesecond activation field 84 is prevented from extending upward and onto first surface due to theconductive ground layer 58. - It should be appreciated that the
conductive ground layer 58 has dimensions such as length and width, which are greater than the length and width of the first andsecond proximity sensors FIGS. 5-7 . As such, theground layer 58 extends beyond the circuit traces forming the proximity sensors so as to enhance the signal isolation provided by theground layer 58 to reduce cross talk or communication of the sensor signals. Theground layer 58 may extend at least one millimeter beyond the peripheral dimensions of theproximity sensors dielectric layers proximity sensors dielectric layers proximity sensors ground layer 58 by a minimum distance, good sensitivity is achieved for the proximity switches. - The
proximity sensors proximity sensor proximity sensors proximity sensor - One example of the printed
ink proximity sensor FIG. 8 having adrive electrode 26 and a receiveelectrode 28 each having interdigitated fingers for generating a capacitive field. It should be appreciated that each of theproximity sensors drive electrode 26 receives square wave drive pulses applied at voltage VI. The receiveelectrode 28 has an output for generating an output voltage VO. While a dual wire capacitive sensor is shown and described herein, it should be appreciated that a single wire capacitive sensor may be employed. It should also be appreciated that theelectrodes - In the embodiment shown and described herein, the
drive electrode 26 of eachproximity sensor electrode 28 to a desired voltage. The receiveelectrode 28 thereby serves as a measurement electrode. When a user or operator, such as the user's finger, enters an activation field, theproximity switch assembly 20 detects the disturbance caused by the finger to the activation field and determines whether the disturbance in eitheractivation fields second sensors proximity switch assembly 20 detects the disturbance of each contacted activation field via separate signal channels. Eachproximity sensor - Referring to
FIG. 9 , theproximity switch assembly 20 for controlling a vehicle window is illustrated according to one embodiment. The first andsecond proximity sensors controller 40, such as a microcontroller. Thecontroller 40 may include control circuitry, such as amicroprocessor 42 andmemory 48. The control circuitry may include sense control circuitry processing the activation field signal associated with eachproximity sensor controller 40 may employ a QMatrix acquisition method available by ATMEL®, according to one embodiment. The ATMEL acquisition method employs a WINDOWS® host C/C++ compiler and debugger WinAVR to simplify development and testing the utility Hawkeye that allows monitoring in real-time the internal state of critical variables in the software as well as collecting logs of data for post-processing. - The
controller 40 provides an output signal to one or more devices that are configured to perform dedicated actions responsive to detected activation of the proximity sensors on the door handle. The one or more devices may include apower window 14. Thepower window 14 may include a conventional power window having a motor that electrically is actuated to drive a window panel between open and closed positions. Thewindow 14 may include a power door window installed in the door of a vehicle to move up and down. According to other embodiments, a movable panel may include a sunroof or moonroof or a rear window panel. It should be appreciated that other devices may be controlled in response to user activation of theproximity switch assembly 20. - The
controller 40 is further shown having an analog to digital (A/D)comparator 44 coupled to themicroprocessor 42. The A/D comparator 44 receives the voltage output VO from each of the proximity sensors 24, converts the analog signal to a digital signal, and provides the digital signal to themicroprocessor 42. Additionally,controller 40 includes apulse counter 46 coupled to themicroprocessor 42. The pulse counter 46 counts the charge signal pulses that are applied to each drive electrode of each proximity sensor, performs a count of the pulses needed to charge the capacitor until the voltage output VO reaches a predetermined voltage, and provides the count to themicroprocessor 42. The pulse count is indicative of the change in capacitance of the corresponding capacitive sensor. Thecontroller 40 is further shown communicating with a pulse width modulateddrive buffer 15. Thecontroller 40 provides a pulse width modulated signal to the pulse width modulateddrive buffer 15 to generate a square wave pulse train VI which is applied to each drive electrode of each proximity sensor 24. Thecontroller 40 processes one or more control routines, shown in one embodiment including awindow control routine 100 stored in memory to monitor user activation of the switch assembly and control movement of the vehicle window. - Operation of the proximity switch assembly may include a user positioning a finger onto the top surface or in close proximity to the top surface of
input member 50 to cause a sufficient disturbance of thefirst activation field 74 to detect user input to close the vehicle window panel. Sensitivity may be adjusted to require that the user press the finger onto thetop surface 50A ofmember 50 to create a sufficient amplitude signal sensed by theactivation field 74. When a user desires to raise the window panel, the user advances the finger forward, aroundinput member 50 and into contact with thebottom surface 50B so as to sufficiently engage thesecond activation field 84 to generate a signal of a sufficient strength indicative of a user input to close the window. When this occurs, the user's hand rotates forward and departs from thetop activation field 74. A signal response to the closing operation is shown inFIG. 10 byline 90A in which the user's finger contacting thebottom surface 50B is shown rising to a first level and then added pressure further processing onto thebottom surface 50B by pulling upwards is indicated by the further rise to the peak amplitude. At the same time, thelower curve 90B shows signal response in thetop activation field 74 where a user's finger may have some interaction with theactivation field 74 which drops off when the user fully extends the finger forward and depresses thebottom surface 50B withinactivation field 84. - The first proximity switch may be configured to momentarily move the window toward the open position for as long as the user's finger is detected on the first proximity sensor based on a first threshold value and may further initiate the demand to fully open the window upon an increase force applied to the top surface by detecting the output of the first proximity sensor relative to a higher second threshold. Similarly, the second proximity switch may momentarily cause the window to move toward the closed position for as long as the user's finger is detected by the second proximity sensor based on a first threshold value and may further activate the window to the fully closed position based on an increase for supply to the bottom surface detected by the second proximity sensor based on a comparison to a second higher threshold. Further, the vehicle may be actuated to the closed position based on sensed signals from both the first and second proximity sensors. In doing so, the proximity switch assembly may detect activation of the bottom second proximity sensor exceeding a threshold combined with the signal detected by the top first proximity sensor being below a threshold.
- The
window control routine 100 is shown inFIG. 11 beginning atstep 102 in a monitoring state. At decision step 104, routine 100 determines whether the window open signal is greater than the window close signal. The open signal is the signal sensed by the first proximity sensor for detecting a window open activation input command, whereas the close signal is the signal generated by the second proximity sensor for sensing a window closing activation input command. If the open signal is greater than the closed signal, routine 100 proceeds todecision step 106 to determine if the open signal is greater than an open threshold, and, if so, determines if the ratio of the close signal to the open signal is less than an open ratio atstep 108. If not, routine 100 is done atstep 122. If the ratio of close to open signals is less than the open ratio, then routine 100 proceeds to step 110 to determine if the open and close signals have been stable for a minimum time period, such as 100 milliseconds, and if so, activates the open enter state and the Wait_For_Release routine atstep 112. Otherwise, routine 100 is done atstep 122. - Returning to decision step 104, if the open signal is not greater than the close signal, routine 100 proceeds to decision step 114 to determine if the close signal is greater than a close threshold and, if not, is done at
step 122. If the close signal is greater than the close threshold, routine 100 proceeds todecision step 116 to determine if a ratio of the open signal to close signal is less than a close ratio and, if not, is done atstep 122. If the ratio of the open to close signal is less than the close ratio, routine 100 proceeds to step 118 to determine if the open and close signals are stable for a predetermined time period, such as 40 milliseconds and, if so, proceeds to step 120 to set the open start equal to open, and to set the ratio start equal to a ratio of open to close, and enters the Wait_For_Pull state. Otherwise, routine 100 is done atstep 122. - Referring to
FIG. 12 , theWait_For_Release state subroutine 200 is illustrated beginning atstep 202 and proceeding todecision step 204 to determine if the open and close signals are less than a release threshold and, if not, is done atstep 206. If the open and close signals are less than the release threshold,subroutine 200 proceeds to step 208 to enter the monitoring state which returns to step 200. - Referring to
FIG. 13 , theWait_For_Pull state subroutine 210 is illustrated beginning atstep 212. Beginning atstep 214, routine 210 sets a ratio equal to the open signal divided by close signal. Next, atdecision step 216, routine 210 determines if the open signal is greater than an open start value multiplied by parameter KD and if the ratio is less than the ratio state multiplied by factor KR, where KD is greater than one and KR is between zero and one. If the conditions ofdecision step 216 are met, routine 210 proceeds to step 220 to activate opening of the window and enters the Wait-For-Release state. Otherwise, routine 210 ends atstep 218. - Accordingly, the
proximity switch assembly 20 advantageously allow for activation of the window based on an object sensed with first and second proximity sensors on first and second sides and isolated by a ground layer. The system and method advantageously allows a user to effectively control the vehicle window without having to actuate a mechanical input lever and with reduced signal interference, and thereby providing for a robust switch assembly having fewer moving parts and which is cost-effective and easy to operate. - It is to be understood that variations and modifications can be made on the aforementioned structure without departing from the concepts of the present invention, and further it is to be understood that such concepts are intended to be covered by the following claims unless these claims by their language expressly state otherwise.
